What is claimed is: 1. An instrumented internal blowout preventer valve for connection between a torque drive system and a drill string, which is rotated by the torque drive system, comprising: a valve housing having an annular groove in which the one or more measurement devices are mounted; and one or more measurement devices mounted to the valve housing for measuring desired drill string drilling parameters during an oil and gas well drilling operation; and a protective sleeve mounted adjacent to the annular groove to protect the one or more measurement devices mounted therein. 2. The valve of claim 1, further comprising an electronics package mounted to the valve housing for recording the desired drill string drilling parameters, and transmitting signals to a drill floor so that a drilling operator may observe the drilling parameters during a drilling operation. 3. The valve of claim 1, wherein an electronics package is mounted in the annular groove of the valve housing. 4. The valve of claim 3, further comprising a protective sleeve mounted adjacent to the annular groove to protect the one or more measurement devices and the electronics package mounted therein. 5. The valve of claim 1, wherein the one or more measurement devices comprise a measurement device calibrated to measure a weight of the drill string. 6. The valve of claim 1, wherein the one or more measurement devices comprise a measurement device calibrated to measure a torque imparted on the drill string. 7. The valve of claim 1, wherein the one or more measurement devices comprise a measurement device calibrated to measure a speed of rotation of the drill string. 8. The valve of claim 1, wherein the one or more measurement devices comprise a measurement device calibrated to measure a vibration imparted on the drill string. 9. The valve of claim 1, wherein the one or more measurement devices comprise a measurement device calibrated to measure an internal pressure of the drill string. 10. The valve of claim 1, wherein mounted within the valve housing is a sealing ball and sealing seats rotatably receiving the ball, such that the sealing ball is movable between an open position and a closed position to allow or prevent, respectively, fluid flow from above and below the ball. 11. An oil and gas well drilling system comprising: a torque drive system having an output shaft; a drill string rotated by the torque drive system; and an instrumented internal blowout preventer valve for connection between the torque drive system output shaft and the drill string, wherein the valve comprises: a valve housing, and one or more measurement devices mounted to the valve housing for measuring desired drill string drilling parameters during an oil and gas well drilling operation. 12. The drilling system of claim 11, wherein the valve further comprises an electronics package mounted to the valve housing for recording the desired drill string drilling parameters, and transmitting signals to a drill floor so that a drilling operator may observe the drilling parameters during a drilling operation. 13. The drilling system of claim 11, wherein the valve housing comprises an annular groove in which the one or more measurement devices are mounted. 14. The drilling system of claim 13, wherein an electronics package is mounted in the annular groove of the valve housing. 15. The drilling system of claim 11, wherein the one or more measurement devices comprise a measurement device calibrated to measure a weight of the drill string. 16. The drilling system of claim 11, wherein the one or more measurement devices comprise a measurement device calibrated to measure a torque imparted on the drill string. 17. The drilling system of claim 11, wherein the torque drive system is a top drive drilling system. 18. A method of measuring desired drill string drilling parameters during an oil and gas well drilling operation comprising; providing a torque drive system; providing a drill string to be rotated by the torque drive system; providing an instrumented internal blowout preventer valve for connection between the torque drive system and the drill string; measuring the desired drill string drilling parameters by use of one or more measurement devices; and recording the desired drilling parameters and transmitting signals representative of the recorded drilling parameters to a receiver by use of an electronics package, wherein the receiver, in turn, passes the signals to an instrument on a drill floor viewable by a drilling operator so that the desired drill string drilling parameters may be observed during a drilling operation. 19. The method of claim 18, wherein the one or more measurement devices comprise a measurement device calibrated to measure a weight of the drill string. 20. The method of claim 18, wherein the one or more measurement devices comprise a measurement device calibrated to measure a torque imparted on the drill string.
