Hub assembly for transmitting a torque, - having a first and having a second connection partner (2, 3), wherein the first and the second connection partner (2, 3) are arranged coaxially with respect to each other with respect to a common main axis, and wherein the first connection partner has a first contact portion and the second connection partner has a second contact portion, wherein the first and the second connection partner (2, 3) are pre-positioned with respect to one another via a form-fitting connection, wherein the first connection partner has a form-fitting contour and the second connection partner has a form-fitting mating contour, - having a plurality of connection elements, wherein the first and the second contact portion (9, 10) each have a plurality of receiving openings for receiving the connection elements, wherein in each case one connection element is guided through a receiving opening of the first contact portion and through a receiving opening of the second contact portion such that the first and the second connection partner (2, 3) are connected to each other for conjoint rotation via the connection elements, wherein, when the receiving openings are correctly positioned in the circumferential direction about the main axis, the form-fitting contour and the form-fitting mating contour can be brought into engagement with each other such that the form-fitting connection is formed and the receiving openings of the first and of the second contact portion (9, 10) are each oriented in pairs in a positionally correct manner with respect to one another in the circumferential direction about the main axis, wherein the receiving openings are arranged congruently with respect to one another, characterized in that in an installation situation, the torque is transmitted from the one connection partner (2, 3) to the other connection partner (2, 3) via the connection elements, wherein the form-fitting connection is not involved in the transmission of torque, but rather serves merely for positioning the connection partners (2, 3) with respect to one another. - having a first and having a second connection partner (2, 3), wherein the first and the second connection partner (2, 3) are arranged coaxially with respect to each other with respect to a common main axis, and wherein the first connection partner has a first contact portion and the second connection partner has a second contact portion, wherein the first and the second connection partner (2, 3) are pre-positioned with respect to one another via a form-fitting connection, wherein the first connection partner has a form-fitting contour and the second connection partner has a form-fitting mating contour, - having a plurality of connection elements, wherein the first and the second contact portion (9, 10) each have a plurality of receiving openings for receiving the connection elements, wherein in each case one connection element is guided through a receiving opening of the first contact portion and through a receiving opening of the second contact portion such that the first and the second connection partner (2, 3) are connected to each other for conjoint rotation via the connection elements, wherein, when the receiving openings are correctly positioned in the circumferential direction about the main axis, the form-fitting contour and the form-fitting mating contour can be brought into engagement with each other such that the form-fitting connection is formed and the receiving openings of the first and of the second contact portion (9, 10) are each oriented in pairs in a positionally correct manner with respect to one another in the circumferential direction about the main axis, wherein the receiving openings are arranged congruently with respect to one another,
