Abstract
A system for precisely aligning two cantilever shafts has a regular polygonal recess having N substantially flat faces on a free end of a first shaft cooperating with N free-rotatable rollers regularly angularly spaced and supported on the free end of the other shaft. The diameter of the circle circumscribed about the rollers is equal to the diameter of the circle inscribed by the N faces of the regular polygonal recess in order to allow introduction of the rollers into the recess when the rollers are aligned with the vertices of the polygonal recess and respective angular rotation of 180/N.degree. between the two cantilever shafts provides precise alignment of the two cantilevered shafts.
