Abstract: A transmission coupling (100), especially a timepiece transmission coupling, for the mechanical linkage of at least one first part (2A) of a first shaft at least movable in rotation about a first axis (A2) to at least one second part (3A) of a second shaft at least movable in rotation about a second axis (A3), the first and second axes being parallel or substantially parallel, the transmission coupling including the at least one first part (2A), the at least one second part (3A), and at least a first elastic return system (15, 16; 18; 16a?-16d?; 111a, 111b; 221, 222, 223, 224) arranged so as to limit or cancel out the play between the at least one first part (2A) and the at least one second part (3A), and connecting the at least one first part (2A) and the at least one second part (3A).

Abstract: Spring (10) for clock mechanism, the spring comprising a body (11) extending between a first end (12) of the spring and a second end (13) of the spring, the spring being intended to be connected mechanically to a housing at each of the first and second ends, the spring comprising, between the first and the second end, at least one member (17) intended to act by contact on an element (42) of the clock mechanism, characterized in that the body comprises a deformable zone (14) extending in a curve (18) and in that the curve comprises a first part (18a) that is concave when viewed from the first end.

Abstract: Spring (30) for clock mechanism, the spring comprising a body (31) extending between a first end (32) of the spring and a second end (33) of the spring, the spring being intended to be mechanically connected to a housing at each of the first and second ends, the spring comprising, between the first and the second end, at least one member (37) intended to act by contact on an element of the clock mechanism.

Abstract: A device (100) for displaying time information with the aid of an indicator member (1), including a cam (2) the profile of which includes a flank (23); a lever (4) driving the indicator member (1); a follower (3) controlling the lever (4), pressed against the cam (2) by first spring means (6), adapted, during movement of the flank (23) in a first direction of movement of the cam (2), to control movement of the lever (4) intended to drive movement of the indicator member (1), characterized in that the follower (3) controlling the lever (4) is adapted to be moved relative to the lever (4) against the return action of second spring means (5) by an action force (F) exerted by the flank (23) of the cam (2) on the follower (3) during movement of the flank (23) in a second direction of movement of the cam (2).
