1. A medical fluid transfer apparatus for transferring a liquid medicament that is hazardous in a fluid-tight sealed manner, the medical fluid transfer apparatus comprising:
a first connector section, which has a first passage and is provided for fluid-tight connection to a medical syringe,
a second connector section, which has a second passage and a third passage, and which is provided for fluid-tight connection to a medical liquid container,
a fluid channel, which extends between the first passage and the second passage and allows a fluid-conducting transfer of the liquid medicament between the medical syringe and the medical liquid container when the fluid transfer apparatus is connected to the medical syringe and to the medical liquid container, and
a compensation container defining a compensation volume that is fluid-tight and variable, which compensation volume is connected in a fluid-conducting manner to the medical liquid container in the connected state of the fluid transfer apparatus by the third passage and is configured for receiving a gas volume displaced from the medical liquid container during the transfer of the liquid medicament,
the first passage and the second passage being connected to one another in a fluid-conducting manner via the compensation volume, and
the compensation volume forming a fluid channel section of the fluid channel.
