An apparatus is provided for use with a shaft mountable gear reduction drive in which a driven shaft is coupled with reduction gears by a hollow intermediate output shaft. The output shaft is journaled within the gearbox and has a tapered axial passage for receiving one end of the generally cylindrical driven shaft. A tapered bushing is wedged into the axial passage to interlock the output shaft and the driven shaft for synchronous rotation. A retaining nut is threaded to the outboard end of the output shaft and is rotated relative thereto to advance the nut axially along the driven shaft and forcefully lock the tapered bushing in place. In order to facilitate the driving engagement of the bushing with the output shaft and driven shaft, a nut locking apparatus is provided for preventing rotation of the retaining nut when the output shaft is rotated by the gear drive, and thereby drawing the tapered bushing along the driven shaft.
