Coupling members to join two rotary members, such that the coupling members () include a unitary body having a first coupling element (), a second coupling element (), and a hub (), wherein the unitary body forms a single piece with the hub () extending between and connecting the first coupling element () to the second coupling element (). The first coupling element () defines a first plane, the second coupling element () defines a second plane with the first and second planes being parallel, and the hub () defines a hub axis normal to the first and second planes. Each of the first and second coupling elements () comprises a plurality of connection elements () arranged about a respective circumference having a respective radius extending from the hub axis, wherein a material of the respective coupling element in a respective circle and in a respective plane is less than the area of the circle. The material forming the first and second coupling elements () is arranged in a respective circumscribing circle over an area less than the total area defined by the circle in the respective plane.
