Abstract
Disposable torque-limiting gearless device with speed reduction. Torque-limiting interfaces having a plurality of undulations arranged around an axial bore or drive socket and separated by a plurality of transition regions configured to engage and disengage to provide torque transmission with predetermined torque limits at various rotational speeds and for amounts of actuations while remaining within a specified operational range. The reduction assembly integral to the gearless torque limiting assembly provides a drive shaft having an input segment, an eccentric segment, and an output segment, wherein the input segment and the output segment each have a centerline running along a same first axis, and wherein the eccentric segment has a center line running along a second axis, the second axis being parallel to the first axis and positioned a first distance away from the first axis.
