ABSTRACT:
A torsion spring coupling for repairing broken torsion springs including at least two mating semicylindrical segment members securable around a torsion bar. The segments are secured between opposing end segments of a broken torsion spring to form a cylinder having threaded outer circumferential surfaces for threadably engaging opposing segments of a broken torsion spring to prevent relative rotational movement between opposing segments of a broken torsion spring longitudinally along a torsion bar.
