Claim 16:
17. A system comprising:
a transmission comprising:
an input member coupled to and configured to rotate with a motor,
an output member, and
an intermediate member that engages the output member, the input member configured to engage the intermediate member and rotate within an open annular space defined by the intermediate member, and when the input member rotates, the output member rotates at a different speed;

one or more clutch surfaces frictionally coupled to the output member;
a compliant member configured to apply an axial preload on the one or more clutch surfaces, the axial preload defining a torque limit;
a constraint ring defining an open annular space where the output member is mounted; and
a constraint bushing mounted between the constraint ring and the output member,
wherein when a torque load on the output member satisfies the torque limit, the output member slips relative to at least one of the one or more clutch surfaces.
