A semiconductor device including a semiconductive body having formed therein an active region and a termination feature which includes spaced field rings disposed around the active region and diffusion rings of the same conductivity type as, but different conductivity than the semiconductive body formed between each pair of field rings. The torque transfer structure includes a first load bearing structure mountable to the rear of the tow vehicle, and a second load bearing structure mountable to the front of the trailer drawbar. Compositions and kits for practicing methods of the invention are also described.
