The coupling device (12) has an unbalanced generator (14) for coupling the excavator attachment to an excavator arm. A passive pivoting device (22) is provided with an excavator-side connecting portion (28) and a device-side connecting portion (30), where the connecting portions are pivoted to each other around a pivot axis (32). The pivot axis is approximately parallel to a surface operated by the excavator attachment.
