A shaft assembly comprises a first shaft and a second shaft. The first shaft has a first end, a second end, and a diametric shoulder. The diametric shoulder is located between the first end and the second end along a first central axis of the first shaft. The second end has at least one axial spline. The second shaft is coupled with the first shaft and has a first end and a second end. The first end of the second shaft has a bore along a second central axis of the second shaft with at least one axial groove. The at least one axial spline is positioned within the at least one axial groove and the diametric shoulder is positioned within the bore.
