A compact heavy duty double universal joint is disclosed. The joint comprises a torque coupler having an interior bore and a pair of bosses adjacent each end, a pair of collars pivotally connect to the bosses, a pair of yokes pivotally connect to the collars and a centering rod assembly in the bore of the coupler. The centering rod assembly is operable, when the operating angle of the joint is not zero, to position the torque coupler so that it splits the operating angle of the universal joint.
