1. A downhole torque limiter, comprising:
a tubular housing;
a pipe positioned within the tubular housing, the pipe transitioning from a larger inside diameter (IDL) to a smaller inside diameter (IDS), thereby forming a venturi profile having a first pressure zone (Z1) and a second pressure zone (Z2);
a tubular valve plate radially positioned between the tubular housing and the pipe and rotationally fixed with the pipe;
a lower sub rotationally fixed relative to the tubular valve plate and the pipe and rotationally coupled to the tubular housing via a clutch mechanism, the tubular valve plate configured to be axially forced uphole by the clutch mechanism when the pipe encounters resistance; and
a valve assembly positioned within a longitudinal opening extending along at least a portion of a sidewall of the tubular valve plate, the valve assembly configured to be activated by a pressure differential created by fluid flowing through the venturi profile, the valve separating the first pressure zone (Z1) and a third pressure zone (Z3).
