      What you have sketched is a rigid-type coupler and not often used for motor connection due to the lack of forgiveness for axial and radial misalignment.

      There are different types of couplers depending on the torque that you need to transmit. From its specification sheet, find the maximum torque that your motor can achieve and choose a coupler size that is 1.5 - 2X that value. Once you know 1) The coupler's torque requirement, 2) the desired physical size (diameter and length) and 3) the bore sizes, you'll be ready.

      R+W (http://www.rwamerica.com) sells bellow and elastomeric couplers that are pretty good.

      If you need more help, Specialty Motions (http://www.smi4motion.com) is a distributor (and manufacturer) of linear motion systems and components. Call or go to the website for help in getting you into the right product for your application.

      Good luck.

      Have a look at the Escogear couplings, widely used in the heavy industrial industry. From small all the way to huge, also available all over the world. Pricey, but you pay for quality.

      You can try this link on McMaster - http://www.mcmaster.com/#shaft-couplings/=ehmrfz
      Check the "Rigid Shaft Couplings" available with them.
      You will find machinable clamp-on shaft couplings which come along with set screws.
      Hope this helps. Good luck!
