Abstract
A friction coupling includes a friction member including a brake surface and a clutch surface in a different plane from the brake surface; a spring abutting the friction member; a brake member proximate to the brake surface; the brake member mounted relative to the friction member to permit relative rotation; and a brake actuator connected to the brake member. The friction member can include an insert.
