Abstract
A system, method and apparatus for a clutch for a well string can include a tubular member, a mandrel, a top sub and a bottom sub. A sleeve can be located between the tubular member and the mandrel. The sleeve has an engaged position wherein an inner sleeve spline is coupled to the mandrel spline, and a disengaged position wherein the inner sleeve spline is uncoupled from the mandrel spline. The sleeve has an outer sleeve spline that is coupled to the tubular spline in the engaged position and the disengaged position. A spring in the tubular member can bias the sleeve from one position to another position. The sleeve can be configured to be moved between the positions to overcome the spring bias.
