Claim 8:
9. A subsurface safety valve (SSSV), comprising:
a valve body including a longitudinal bore extending axially through the valve body, the longitudinal bore operable to convey subsurface production fluids there through;
a bore closure assembly disposed proximate a downhole end of the longitudinal bore;
a bore flow management actuator disposed in the central bore;
a mechanical linkage coupled to the bore flow management actuator, the mechanical linkage operable to move the bore flow management actuator between a closed state and a flow state to engage or disengage the bore closure assembly to determine a flow condition of the subsurface production fluids through the central bore;
a drive assembly coupled to the mechanical linkage; and
a clutch assembly positioned between the drive assembly and the mechanical linkage, the clutch assembly including:
an output coupler housing configured to couple to a lead screw of the mechanical linkage, the output coupler housing having a central opening extending at least partially therethrough;
an input shaft located at least partially within the central opening of the output coupler housing, the input shaft coupled to an output of the drive assembly;
an electromagnet coupled to the input shaft, the electromagnet configured to axially translate the output coupler housing from a de-coupled state to a coupled state when the electromagnet is energized; and
one or more grooves located in one of an outer surface of the input shaft or an inner surface of the central opening and one or more engagement members located in the other of the inner surface of the central opening or the outer surface of the input shaft, wherein:
the one or more engagement members are configured to not engage with the one or more grooves when the output coupler housing is in the de-coupled state to allow the input shaft and the output coupler housing to freely rotate relative to one another; and
the one or more engagement members are configured to engage with the one or more grooves when the output coupler housing is in the coupled state to rotationally fix the input shaft and the output coupler housing relative to one another.
