A coupler assembly is installed between a driving shaft and a driven shaft to transmit rotary power and motion at constant velocity at all times during their relative positioning varying from zero degree in line to ninety degree angularity as selected throughout a hemisphere of possible radial shaft directions. In a preferred embodiment four pairs of yokes or links are equally spaced both radially and circumferentially about the inline centerline of the driving and driven shafts. Four yokes or links are rotatably, slidably and/or reciprocatably contained, in respect to either the driving or driven shaft, by positioning their rod ends partially confined within individual cylinders formed in an overall cylindrical body; in turn secured to either the driving or driven shaft. These four yokes or links have their cantilevered extending connectable ends, each with a pair of opposed confronting arms, and each confronting arm with a pin positioned ball, positioned for a linking interconnection to like cantilevered extending connectable ends of the four yokes or links rotatably, slidably and/or reciprocatably contained with respect to another overall cylindrical body. The final interconnection of these four yokes or links at these balls is undertaken by using hubs which are secured about the pin positioned balls of the opposed confronting arms.
