1. A system, comprising:
a chassis, comprising:
a housing;
a support spindle mounted for rotation relative to the housing;
a splined member mounted for rotation relative to the housing; and
a spring rotationally biasing the splined member toward a home position; and
a handle, comprising:
a shank extending along a rotational axis of the handle, wherein the shank includes a proximal section, a distal end section, and an intermediate section positioned between the proximal section and the distal end section; and
a manually graspable portion extending from the shank and formed closer to the proximal section than to the distal end section;
wherein the proximal section comprises a proximal opening defined in part by a pair of proximal portion sidewalls, and wherein the rotational axis extends between the proximal portion sidewalls;
wherein the intermediate section comprises an intermediate opening that receives the support spindle, wherein the intermediate opening is defined in part by a pair of intermediate portion sidewalls that closely engage the support spindle; and
wherein the distal end section comprises a distal opening that receives the splined member, and wherein the distal end section comprises an active section including at least one protrusion operable to engage at least one spline of the splined member such that the active section is rotationally coupled with the splined member.
