This invention is a mechanical power transmission device that can transfer power from a source like an engine to a load with automatic conversion of torque. It consists of mainly two components- the transmission plate and the lever disc. The transmission plate has a uniform well for the size of the lever disc to be placed inside and a transmission bolt mechanism that connects them. The input torque is brought at the centre of the transmission disc whereas the output torque is derived at the centre of the lever disc, by an input and out shaft respectively. There is also a cover disc that covers the connected lever disc inside the well of the transmission disc. This device can be used in various situations like in automobiles, motorcycles, industry or such areas where torque conversion is necessary and is efficient due to its simplicity and being a purely mechanical device.
