Abstract
A torque-limiting coupler for connecting an electric motor to a rotatable input of a vehicle is provided, including: a rigid frame that is configured to be coupled to one of the rotatable input or an output shaft of the electric motor; and an clastic member, configured to engage the other of the rotatable input or the output shaft of the electric motor, that engages the rigid frame such that the elastic member substantially maintains its shape and inhibits angular displacement between the rotatable input and the output shaft when an amount of torque received from the output shaft is below a predetermined torque limit, the elastic member changes shape permitting angular displacement between the rotatable input and the output shaft when an amount of torque received from the output shaft exceeds the predetermined torque limit.
