Torque transferring coupler

A torque transferring coupler, comprising:

• an inner cylinder, wherein the inner cylinder comprises a central portion and a lower portion comprising first wave splines, wherein an upper axial face of the first wave splines is defined by an upper outer edge and an upper inner edge along which the central portion and the first wave splines connect, wherein the upper axial face has a uniform radial thickness defined by a radial distance between the upper inner edge and the upper outer edge, and wherein an axial length of the lower portion of the inner cylinder varies in an oscillating manner as the inner cylinder rotates about its axis to form a first wave profile corresponding to shapes of the first wave splines;
• and
• an outer cylinder, wherein the outer cylinder is hollow and comprises second wave splines, wherein the second wave splines have a lower axial face defined by a lower outer edge and a lower inner edge, wherein the lower axial face has a uniform radial thickness defined by a radial distance between the lower inner edge and the lower outer edge, and wherein an axial length of the second wave splines varies in an oscillating manner as the outer cylinder rotates about its axis to form a second wave profile corresponding to shapes of the second wave splines, wherein a coupling is formed in response to a section of the outer cylinder disposed to surround a portion of the inner cylinder and the first wave splines disposed to interlock with the second wave splines.
