1. A power tool ensemble, comprising:
a power head, including:
a motor; and
a power shaft mechanically coupled to the motor;
a first shaft coupler, including:
a first power shaft connecter configured to be capable of being mechanically coupled to the power shaft;
a first shaft-specific connecter having a first tool shaft configuration configured to be capable of being mechanically coupled to a first tool shaft of a first tool head, the first shaft-specific connecter being coupled to the first power shaft connecter; and
a first coupler housing around the first power shaft connecter and the first shaft-specific connecter, wherein the first power shaft connecter and the first shaft-specific connecter are rotationally supported in the first coupler housing; and
a second shaft coupler, including:
a second power shaft connecter configured to be capable of being mechanically coupled to the power shaft;
a second shaft-specific connecter having a second tool shaft configuration configured to be capable of being mechanically coupled to a second tool shaft of a second tool head, the second shaft-specific connecter being coupled to the second power shaft connecter; and
a second coupler housing around the second power shaft connecter and the second shaft-specific connecter, wherein the second power shaft connecter and the second shaft-specific connecter are rotationally supported in the second coupler housing;
