Claim 8:
9. A rotational phase adjustment method for a coupling device configured to transmit a rotational force between a first shaft and a second shaft,
the coupling device including:
a first coupling member configured to relatively non-rotatably be mounted on the first shaft;
a second coupling member configured to relatively non-rotatably be mounted on the second shaft; and
an intermediate member disposed between the first coupling member and the second coupling member in an extension direction of an axis of the coupling device, and configured to allow misalignment between the first shaft and the second shaft,
the second coupling member including:
a base member configured to be fixed to the intermediate member by a first bolt; and
a shaft mounting member configured to relatively non-rotatably be mounted on the second shaft, the shaft mounting member having a slot extending along a circumferential direction of the axis and being configured to detachably be fixed to the base member by a second bolt inserted through the slot,
wherein the first coupling member includes a first flange portion extending along a direction intersecting with the axis, and
wherein the first flange portion includes a first coupling-side fastened portion configured to be fastened to the intermediate member by a third bolt, and a first escape recess formed on an end surface on a side of the intermediate member and configured to allow a head portion of the first bolt to be housed in the first escape recess,
the rotational phase adjustment method for the coupling device, comprising:
a relative rotation step of relatively rotating the shaft mounting member to the base member; and
a fixing step of fixing the shaft mounting member to the base member by the second bolt, after the relative rotation step.
