Abstract: A device for manually rotating a shaft in a substantially continuous manner, the device having a coiled spring-like body having at least one and a half coils, a pair arms extending laterally from the ends of the body, each arm integral with one of the coils, and an extension handle coupled to the end of each arm. The extension handles can be telescopically adjustable if desired. Further, the wrench can be permanently mounted on the outer surface of a shaft to enable convenient rotation of the shaft without additional tools. Additionally, the shaft and wrench assembly can form a component of an electrical pressure switch or like apparatus.
