The disks of this coupling converge towards the outside in a way to minimize the bending stresses in general, and especially when the coupling axes intersect at an angle, kept quite small. The bending stresses are kept approximately equal at the outside end and at the inside end of the working portion of the disks. This is attained with the disk shape. Opposite disk profiles of axial sections have general directions or mean tangents that intersect in the average at a radius double their mean radius, and more generally at a radius from the disk axis between (2 + 1/8) and (2 - 1/8) said mean radius.
