A digital display module for a torsion wrench includes a housing sleeved on a shank of the torsion wrench. A microprocessor is disposed in the housing and includes a normal display model and an inverted display model therein, wherein the normal display model is provided for right-handed operator and the inverted display model is provided for left-handed operator. Multiple function keys are arranged on the periphery of the housing for selecting display models and inputting data. A display screen is mounted on the periphery of the housing and electrically connected to the microprocessor. The display screen is divided into a first display zone for showing numeral and a second display zone for showing scale ratio. A sensor is mounted on a torsion unit of the torsion wrench and electrically connected to the microprocessor for sensing the operating torsion and transmitting torsion data to the microprocessor.
