Abstract: The present invention relates to a shaft coupling which comprises a first shaft (1) supported by a bearing at a first end (1-1), and a second shaft (2) supported by a bearing at a second end (2-2). Said first shaft (1) and second shaft (2) are coaxially arranged so that the second end (1-2) of the first shaft (1) is against the first end (2-1) of the second shaft (2). On an end surface of the second end (1-2) of the first shaft (1), there is a recess (6), and a protrusion (7) protrudes from the end surface of the first end (2-1) of the second shaft (2), and said recess (6) receives said protrusion (7). The shaft coupling comprises only one third bearing (8), as well as a coupler (9) which receives the second end (1-2) of the first shaft (1) and the first end (2-1) of the second shaft (2). With such a solution, a greater radial error may be allowed between the shafts without the structures of the coupling point being overloaded.
