The present invention provides polygonal connections for connecting a shaft with a flange. In a preferred embodiment, the polygon connection includes a polygon shaped recess in the flange, a polygon shaped terminus on the shaft, an outward projection on the terminus, and a groove on the flange. The cross sections of the recess of the flange and the terminus of the shaft are preferably complimentary polygon shapes so that the recess fittingly receives the terminus. An inward projection and ridge cooperatively define the groove of the flange. The groove axially retains the flange on the terminus. |
