Abstract: For improving manual operation of an actuator (1), a novel clutch (4, 6) is proposed that features at least one movable protrusion (12) that is axially movable along a coupling axis (11) of the clutch (4, 6) relative to an element (8) that carries the protrusion (12). This design has the advantage that engagement of the clutch (4, 6) is possible under all circumstances, even in cases in which the protrusion (12) is not yet in a correct rotational coupling position (18) (cf. FIG. 7), as the protrusion (12) can be transferred into the coupling position (18) by a rotational movement (24, 25) at all times.

Abstract: An actuating drive (2) including a ball screw drive (3) for activating a self-closing, linearly activated fitting (4) and a method of use are provided. While the opening of the fitting (4) with the actuating drive (2) takes place by an electric motor by the ball screw drive (3), a restoring movement is transmitted to the spindle (6) when closing the automatically closing fitting (4). The restoring movement, and thus also a closing movement of the fitting (4), can be at least indirectly decelerated by way of the ball screw drive (3), this being able to protect the fitting (4) and ultimately also the ball screw drive (3) and optionally further components connected to the fitting (4) and/or the ball screw drive (3) from damage, and facilitating a fail-safe function.

The cam disc (8) has a control cam (10), the profile of which is adapted to a spring characteristic curve of the restoring element such that, in the case of activation of the failsafe drive (1), a constant output movement and/or a constant output torque can be generated.
