Non-destructively decoupling electric actuator of downhole flow control device

A method comprising:

• deploying a shifting tool to a downhole location in a wellbore of a hydrocarbon well to manually operate an electronic flow control device, the electronic flow control device further comprising:
• a device body, a flow control component concentrically arranged within the device body and linearly displaceable relative thereto, an actuator assembly residing within the device body and operated to linearly displace the flow control component relative to the device body, the actuator assembly including a linearly displaceable actuator coupling element, and an override assembly including a floating shifting member concentrically arranged within the flow control component and limitedly linearly displaceable relative thereto, and a flexible flow control component coupling element associated with the flow control component and non-permanently deflectable in a radially outward or radially inward direction to respectively engage with or disengage from the actuator coupling element of the actuator assembly, engaging the shifting tool with the floating shifting member of the flow control component;
• and non-destructively decoupling the flow control component from the actuator assembly by applying a linear displacement force to the floating shifting member by the shifting tool in one of a first direction or a second direction that causes the floating shifting member to be linearly displaced from a first position where the floating shifting member maintains a coupled relationship of the flow control component coupling element and the actuator coupling element, to a second position where the flow control component coupling element is unsupported by the floating shifting member and the flow control component coupling element and the actuator coupling element are resultantly non-destructively decoupled by an inward deflection of the flow control component coupling element such that the actuator assembly is capable of recoupling to the flow control component to resume operating the flow control component.
