A power coupler for transferring rotary power from a rotary power device to a load device includes a shear thickening fluid (STF) and a chamber that contains the STF. The power coupler further includes a drive shaft housed radially within a drive side section of the chamber and protruding outward from an end of the chamber for coupling to the rotary power device. The power coupler further includes a load shaft housed radially within a load side section of the chamber and protruding outward from another end of the chamber for coupling to the load device. The power coupler further includes a drive turbine housed radially within the drive side section and coupled to the drive shaft. The power coupler further includes a load turbine housed radially within the load side section at a fixed operational distance from the drive turbine and coupled to the load shaft.

An assembly for inclusion between a drill bit and a drill string, the assembly having an overrunning clutch mechanism that disengages the drill bit from the drill string during the slip portion of a stick-slip cycle to allow the drill bit to freely rotate faster than the drill string. The assembly further includes a rotational vibration dampener operatively connected between the overrunning clutch and the drill bit. The vibration dampener may include a fluid chamber with viscous fluid or restrictions to fluid flow to effect dampening. During normal operation, the one-way overrunning clutch remains engaged to transfer torque between the drill string and bit, while the torsional damper is in its maximum displaced position to transfer the load. During slip, the drill bit is disengaged until its speed is lower than the drill string speed. Torsional vibration dampener dampens sudden impulse force of the overrunning clutch re-engaging.

A power shunt for shunting rotary power from a load device includes a shear thickening fluid (STF) and a chamber that contains the STF. The power shunt further includes a drive shaft housed radially within a drive side section of the chamber and protruding outward from an end of the chamber for coupling to a lock configured to prevent rotation of the drive shaft. The power shunt further includes a load shaft housed radially within a load side section of the chamber and protruding outward from another end of the chamber for coupling to the load device.

A connection system for components includes a first component having a first shaft, and a second component having a second shaft. The connection system includes a sleeve coupled to the second shaft that includes a chamber to be disposed about a portion of the first shaft, and a valve fluidly coupled to the chamber. The connection system includes a piston defining an inner piston bore. The piston is coupled to the second shaft and movable relative to the second shaft. The connection system includes a valve actuation member received within the inner piston bore and movable relative to the piston. The piston is to move relative to the second shaft to couple the sleeve to the first shaft in a first state and the valve actuation member is to move relative to the piston to uncouple the sleeve from the first shaft in a second state.
