Claim 17:
18. A coupling assembly adapted for use on rock crusher having an upper rotating shaft and a lower rotating shaft, said coupling assembly comprising:
an eccentric axis plate, said eccentric axis plate including:
an eccentric axis plate top surface that is operatively connected to the upper rotating shaft of the rock crusher;
an eccentric axis plate bottom surface that is spaced apart from the eccentric axis plate top surface and has a drive tang extending therefrom;

a slider plate, said slider plate including:
a slider plate top surface that is in operational contact with the drive tang of the eccentric axis plate bottom surface and has a top groove therein;
a slider plate bottom surface that is space apart from the slider plate top surface and has a bottom groove therein;

an adapter plate, said adapter plate including:
an adapter plate top surface that is in operational contact with the slider plate bottom surface and has an adapter plate tang extending therefrom;
an adapter plate bottom surface that is spaced apart from the adapter plate top surface and operatively connected to the lower rotating shaft of the rock crusher;

wherein the upper rotating shaft has a first longitudinal axis; and wherein the lower rotating shaft has a second longitudinal axis; and wherein the first longitudinal axis and the second longitudinal axis are non-parallel; and wherein the coupling assembly is adapted to couple the upper rotating shaft and the lower rotating shaft; and wherein the drive tang of eccentric axis plate and the top groove of the slider plate comprise an involute arc that is concentric to an intersection of the non-parallel first longitudinal axis and the second longitudinal axis.
