A friction coupling (20) comprising a friction member (21) including a brake surface (21d) and a clutch surface (21c) in a different plane from the brake surface, a spring (22) abutting the friction member, a brake member (23) proximate to the brake surface (21d), the brake member mounted relative to the friction member (21) to permit relative rotation, and a brake actuator (24) connected to the brake member.
