1. A clutched device comprising: a pulley; a shaft member; a first one-way clutch having a first wrap spring; and an actuator having an electromagnetic coil and an armature; wherein the first one-way clutch rotationally couples the pulley and the shaft member when the actuator is actuated and rotary power is transmitted from a first one of the pulley and the shaft member to the other one of the pulley and the shaft member in a first rotational direction; and wherein a frictional force is applied to the armature when the actuator is activated, the frictional force being configured to resist rotation of the armature to cause the first wrap spring to radially expand into driving engagement with a clutch surface that is coupled to the pulley for common rotation.
