1. A torque transfer assembly comprising:
a drive shaft of a drive unit, the drive shaft including external splines, a first proximal groove extending around the drive shaft, and a first distal groove extending around the drive shaft, the first proximal groove and the first distal groove are spaced apart at a first distance;
a driven member including a hub configured to receive the drive shaft therein, the hub including internal splines configured to mesh with the external splines, a second proximal groove, a second distal groove, and a slit extending through the hub, the second proximal groove and the second distal groove are spaced apart at a second distance that is equal to the first distance;
a first retention member configured to be inserted into the slit and into cooperation with the first proximal groove of the drive shaft when the drive shaft is seated in the hub; and
a second retention member configured to be seated between the drive shaft and the hub in the first distal groove of the drive shaft and the second proximal groove of the hub when the drive shaft is seated in the hub;
wherein the first distal groove of the drive shaft aligns with the second proximal groove of the hub when the drive shaft is positioned within the hub such that the first proximal groove of the drive shaft is aligned with the slit of the hub.
