The pilot reported that while cruising at 600 feet above ground level, the helicopter shook violently. He commenced an autorotational landing and the helicopter landed heavily a short time later. A post-flight inspection revealed that the transmission torsion coupling had broken, and two steel back up pins had sheared. The transmission failure had caused complete loss of torque to the main rotor. The tail rotor and gear box showed no evidence of pre-impact damage.
