The device consists of a tapered spline coupler for a drive shaft of a pull-type forage harvester. The first drive shaft and second drive shaft each have a set of tapered splines that are inserted into a tapered, internally splined coupler. A pair of retaining rings affixed to the drive shafts draws the shafts into the coupler. A retaining bolt may be tightened to force the shafts into the coupler.
