An axial torque coupling between a pair of adjacent rotating machine wheels comprising a first wheel having a first plurality of axially extending knuckles, the first plurality of knuckles spaced circumferentially in an annular array with first slots therebetween, and a second wheel having a second plurality of axially extending knuckles, the second plurality of knuckles spaced circumferentially in an annular array with second slots therebetween; and wherein the first plurality of knuckles are received in the second slots and the second plurality of knuckles are received in the first slots, each of the first plurality of knuckles engaging an adjacent one of the second plurality of knuckles only on a single radial surface.
