The invention relates to a method (100) for congruent alignment of a first polygonal multi-edge geometry (2) of a rotor shaft (3) of a dynamic mixer (4) with a second polygonal multi-edge geometry (5) of a drive shaft (6) of a motor (7) of a mixing apparatus (8), and optionally insertion of the second polygonal multi-edge geometry (5) of the drive shaft (6) of the motor (7) of the mixing apparatus (8) into or onto the first polygonal multi-edge geometry (2) of the rotor shaft (3) of the dynamic mixer (4), as well as a dynamic mixer for use in the method as also use of the mixer in the method.

A receiving device to form a manufacturing apparatus when the receiving device is inserted into a mixing machine, includes a first receiving location configured to receive a first capsule containing a first formulation, a second receiving location configured to receive a second capsule containing a second formulation, a first bearing element located at the level of a first actuation face of the receiving device and movable inside the first receiving location, to exert a force on the first capsule, and/or a second bearing element located at the level of a second actuation face, preferably opposite to the first actuation face, and movable inside the second receiving location, in order to exert a force on the second capsule, wherein at least one bearing element is a vane movable in rotation about a hinge, the movable vane being configured to enter one of the first and second receiving locations.
