1. A coupler to transfer controller motion from a robotic manipulator, the coupler comprising:

  • a pin having a tip with a spherical bearing surface; and

    a plate supported on the spherical bearing surface of the pin with two degrees of freedom about the center of the spherical bearing surface, the plate having a back surface and an opposing driving surface that bears against a first surface of an inner gimbal of a gimbal assembly of a driven device, the plate including a pin receiving portion that extends outwardly from the driving surface and away from the back surface, the pin receiving portion including a spherical receiving surface to receive the spherical bearing surface of the pin, the spherical bearing surface being located at a distance above the driving surface such that the center of the spherical bearing surface coincides with an intersection of the gimbal assembly axes of the driven device.
