Abstract: A method and several mechanisms for carrying out the method are disclosed. The method of (1) generating torque pulses by engaging a drill bit on the lower end of a rotating drill string in the bottom of a wellbore, and (2) monitoring the top of the drill string for the torque pulses therein may be practiced by a drill bit disconnectably attached with a coupling to the lower end of a drill string in a wellbore for being momentarily and precisely uncoupled and coupled during drilling to interrupt the torque transmission for generation of torque pulses in the drill string for being monitored at the surface. Mechanical, electrical, and fluid operated couplings are disclosed for rapidly coupling and uncoupling the drill bit from the drill string.
