1. A cone friction clutch for engaging a shaft, the clutch comprising: a carrier having a tapered bore and an external gear defined thereon; a tapered piston rotating with the shaft within the bore; a split ring spring outside the tapered piston; means for moving the tapered piston into contact with the carrier; and means for controlling movement of the piston, wherein the means for controlling movement causes the means for moving to move the tapered piston into contact with the carrier, and power is transmitted between the carrier and the shaft. 2. The clutch of claim 1 wherein the means for moving is selected from a group consisting of a ball and ramp, a solenoid, and a hydraulic mechanism. 3. The clutch of claim 1 wherein the means for controlling is selected from a group consisting of a computer, a microprocessor controller, an electronic control unit, a hydraulic controller, an engine control unit, an antilock brake system controller, a traction system controller, and an engine electronic controller. 4. The clutch of claim 1 wherein the means for moving is selected form a group consisting of a ball and ramp, a solenoid, a hydraulic mechanism, an electric motor and a hydraulic pump. 5. The clutch of claim 2 further comprising a differential gear set attached to the carrier and a first and a second shaft, the first shaft in contact with the tapered piston for controllable contact with the tapered bore. 6. A limited slip differential for an automobile having a rear differential and two half-axles, the limited slip differential comprising: a carrier having a tapered bore and an external gear defined thereon for interfacing with a drive shaft, the carrier in geared contact through a set of differential gears with a first and a second half-axle; a tapered piston for rotating with the first half-axle within the bore; a split ring spring for rotation with the tapered piston: a mechanism for moving the tapered piston, the mechanism selected from a group consisting of a ball and ramp mechanism, a hydraulic pump, and a solenoid; and a controller for controlling movement of the tapered piston, wherein the controller controls movement of the piston into contact with the carrier, and power is transmitted between the first half-axle and the carrier. 7. A coupling for use in a power transmission having an auxiliary driving shaft, the coupling comprising: a carrier having a tapered bore and an external gear defined thereon; a tapered piston within the bore for rotating with the auxiliary driving shaft; a split ring spring for rotation with the tapered piston; a mechanism for moving the tapered piston, the mechanism selected from a group consisting of a ball and ramp mechanism, a hydraulic pump, and a solenoid; and a controller for controlling movement of the tapered piston, wherein the controller controls movement of the mechanism and the piston into contact with the carrier, and power is transmitted from the carrier to the auxiliary driving shaft. 8. The coupling of claim 7, wherein the auxiliary driving shaft is selected from a group consisting of a differential power shaft, a half-axle, and a power take-off shaft. 9. The coupling of claim 8, wherein the controller is selected from a group consisting of a computer, a microprocessor controller, an electronic control unit, a hydraulic controller, an engine control unit, an antilock brake system controller, a traction system controller, and an engine electronic controller.
