A first end of the outer sleeve terminates in a radially extending flange larger than the aperture. A second end of the outer sleeve is opposed to the first end.

Abstract: A drive assembly coupler to transfer torque from a motor shaft. The coupler includes a body having a first end, a second opposed end, and an axial opening through the body extending between the ends. A first pair of opposed channels is provided in the body, each channel parallel to the other and parallel to the opening. A second pair of opposed channels is provided in the body, each channel parallel to the other and parallel to the opening. A first U-shaped insert has a threaded opening receivable in the first end and has a first pair of extending legs receivable in the first channels. A second U-shaped insert has a threaded opening receivable in the second end and has a second pair of extending legs receivable in the second channels.
