Cable wrap clutch with torque limiter shutoff and operator controlled re-engagement

A rotational coupling device, comprising:

• an input hub disposed about an axis of rotation;
• an output hub disposed about the axis of rotation on a first axial side of the input hub;
• an attachment ring disposed about the axis of rotation on a second axial side of the input hub opposite the output hub;
• and,
• a cable disposed radially outwardly of the input and output hubs, the cable having a first end coupled to the output hub and a second end coupled to the attachment ring and configured to couple the input and output hubs together for rotation during rotation of the input hub in a first rotational direction;
• a torque limiter having
• a torque transmission plate configured for rotation with the input hub and axially movable along the axis of rotation, the torque transmission plate biased in a first axial direction towards engagement with the attachment ring;
• and,
• an armature plate fixed against rotation, but axially movable along the axis of rotation, the armature plate configured for axial movement with the torque transmission plate along the axis of rotation;
• an electromagnet disposed on one side of the torque limiter opposite the input hub, the electromagnet configured, when energized, to attract the armature plate and torque transmission plate in a second axial direction away from the attachment ring.
