US Patent 11283217 Torque-limiting torque sleeve with fail-safe failure mode

A torque-limiting torque sleeve may include an inner sleeve and an outer sleeve configured to be coupled to one another in a coaxial arrangement such that the outer sleeve is fixed relative to the inner sleeve in the longitudinal direction. A first end of the outer sleeve overlies a first end of the inner sleeve, and a second end of the inner sleeve extends from the outer sleeve. A torque limiting feature is configured such that rotation of the outer member in a first direction enables tightening of a coupler on an interface port up to a predetermined torque limit, and rotation of the outer member in a second direction opposite to the first direction loosens the coupler on the interface port.
