An electrical power device (30) for mounting on a vehicle includes a drive coupling (44, 100, 120) for rotationally coupling the rotor (46) of the power device to the axle and wheel assembly (12) of the vehicle. The drive coupling includes a drive shaft (60, 122) having a portion extending outwardly into proximity with a projection (48) on the vehicle axle. A crank arm (74, 128) extends from the drive shaft for engaging the projection so that when the axle is rotated, the projection engages the crank arm and thereby rotates the drive shaft of the power device.
