Abstract

A first torque coupler adapted for use with a second torque coupler having first and second lugs spaced apart by a first distance includes a support, a first member rotatably coupled to the support and including a third lug, and a second member rotatably coupled to the support and including a fourth lug. The first and second members engage one another to prevent unrestricted rotation of the first and second members in the same direction. The first and second members are rotatable in opposite directions when in engagement with at least one of the first and second lugs to move at least one of the third and fourth lugs, a first torque transmitting position in which the third and fourth lugs are spaced from one another by a second distance substantially equal to the first distance to a second position in which the third and fourth lugs are spaced from one another by a third distance unequal to the first distance.
