A torque sensing device comprises a torque sensor (30) and a transmission mechanism (20). The torque sensor includes an outer tube (31) and a first strain gauge (32). The outer tube (31) has a main tube part (311) and a first deformable part (33). 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 (A1) 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.
