A universal coupler for use on a tower leg assembly of an irrigation system for joining an outboard drive shaft of a drive wheel gear box of circular cross-section and known size to a motor-driven square drive shaft of unknown size. The universal coupler includes, along a first longitudinal end thereof, a shaft receiving structure for fixedly containing the outboard drive shaft, and along the opposite longitudinal end, a V-shaped cradle dimensioned to accommodate therein adjacent flat wall surfaces of the square drive shaft. A flexible, shock absorbing disk joins the V-shaped cradle and the outboard drive shaft receiving structure in a manner whereby each shaft is rotated at the same speed in response to a rotational force imparted on the other. L-shaped bolts are provided to facilitate clamping the square drive shaft to the V-shaped cradle using fasteners.
