An actuator and clutch assembly for a power transmission device includes a first and second clutch members arranged to selectively define a connected state of the clutch when the second clutch member is drivingly engaged with the first clutch member and a disconnected state of the clutch when the second clutch member is not drivingly engaged with the first clutch member. An electric motor drives an input member driven for rotation about an axis, and an output member is driven axially relative to the input member when the input member rotates, wherein the second clutch member moves axially with the output member. A spring provides a force on the output member that biases the output member in a direction in which the second clutch member is moved toward the first clutch member. The spring is radially and axially overlapped by the input member and the output member.

The disclosure relates to an overrunning clutch, comprising a torque-introducing clutch element, a torque-receiving clutch element and switching element, which is forced from an engagement position into a freewheeling position or from a freewheeling position into an engagement position in dependence on the direction of a sufficient change in the rotational angle position between the torque-introducing clutch element and the torque-receiving clutch element by means of an actuating force applied to the switching element by an actuator. According to the disclosure, the actuating force is a friction-induced actuating force, which is induced by means of a friction-force pairing between the actuator and a component of the overrunning clutch that is in frictional contact with the actuator and the actuator forms an interlockingly acting actuating stop, by means of which the actuating force acts on the switching element.
