Claim 20:
21. A downhole connection, the downhole connection comprising:
a rotating member;
an independently rotating member rotatable relative to the rotating member, the independently rotating member including a solenoid rotationally fixed to the independently rotating member; and
a moving member connected to the rotating member, the moving member being movable by the solenoid and connected to an actuation valve of a downhole tool rotationally connected to the rotating member, wherein the actuation valve includes:
a cylindrical piston with piston threads on an inside of the cylindrical piston, the cylindrical piston being longitudinally movable relative to the solenoid;
a rotor having rotor threads threaded into the cylindrical piston threads such that as the piston moves longitudinally, the rotor rotates in conjunction with the rotor threads threaded into the piston threads, the rotor including a paddle with a rotor opening; and
a partition connected to the rotor at the paddle, the partition having a port, wherein in a first rotor position, the rotor opening and the port are misaligned such that no fluid passes through either the rotor opening and the port, and in a second rotor position, the rotor opening and the port are at least partially aligned such that fluid may pass through a combined opening of the rotor opening and the port.
