Claim 7:
8. A transmission assembly, 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;

a first friction surface frictionally coupled to both a distal side surface of the output member;
a second friction surface frictionally coupled to a proximal side surface of the output member;
a compliant member configured to apply an axial preload on the first and second friction surfaces, the axial preload defining a torque limit, and when a torque load satisfies the torque limit, the output member slips relative to at least one of the first or second friction surfaces; and
an output member disposed between and interfacing with the first friction surface and the compliant member.
