An overload torque clutch in which a pair of slidable fingers on a driving member engage rigidly mounted stops on a coaxially mounted driven member. The slidable fingers are held in the engaged position by a transverse resiliently loaded yoke member which locates in specially designed recesses in the fingers. At a predetermined torque level of the fingers are forced out of contact with the stops and the yoke rides out of the recesses against the action of the resilient loading. The clutch may be reset manually, hydraulically or pneumatically. The device is particularly useful as a safety clutch to disengage heavy-duty equipment, such as conveyor belt systems, from an electric drive in the event of jamming or the like.
