A torque sensing device comprises a torque sensor and a transmission mechanism. The torque sensor includes an outer tube and a first strain gauge. The outer tube has a main tube part and a first deformable part. The main tube part is connected to and surrounds a crankshaft of the transmission mechanism. The first deformable part is connected to the main tube part. The first deformable part extends circumferentially around the crankshaft between a first and a second side. The first deformable part has a first included angle defined between a first line extending through a center of the crankshaft and a first side and a second line extending through the center of the crankshaft and a second side. The first included angle is less than 180 degrees. The first strain gauge is attached to the first deformable part.
