COUPLING DEVICE AND ROTATIONAL PHASE ADJUSTMENT METHOD FOR COUPLING DEVICE

A coupling device configured to transmit a rotational force between a first shaft and a second shaft, the device including a first coupling member mounted on the first shaft, a second coupling member mounted on the second shaft, and an intermediate member disposed between the first coupling member and the second coupling member, and configured to allow misalignment between the first shaft and the second shaft. The second coupling member includes a base member configured to be fixed to the intermediate member by a first fastening device, and a shaft mounting member configured to relatively non-rotatably be mounted on the second shaft, the shaft mounting member having a long hole extending along a circumferential direction of the above-described axis and being configured to detachably be fixed to the base member by a second fastening device inserted through the long hole.
