Abstract: A clutch, comprising a clutch disk (12), a calliper means (10) which carries opposite friction pads (24, 25) between which the clutch disc (12) is accommodated, said clutch disc (12) and calliper means (10) each being connected to one of an ingoing (9) and an outgoing (13) member, biasing means (32) for urging the opposite friction pads (24, 25) into frictional engagement with the clutch disc (12), motor means (2, 3) as well as screw actuation means (17-22) which are driveable by the motor means (2, 3) for displacing the opposite friction pads (24, 25) with respect to each other against the biasing force exerted by the biasing means (32), characterized in that the screw actuation means comprise two screw/nut actuators (17-22) with opposite screws threads, which disc (12), one of the nut (17, 18) and screw (21, 22) of each actuator being notably supported with respect to either the ingoing (9) or the outgoing (13) member, and the other of said nut (17, 18) and screw (21, 22) of each actuator engaging the oppos
