1. A safety module for a process valve, comprising:
a first interface having electrical lines and fluid lines for being complementary to a first connection interface of a drive module of the process valve and a second interface having electrical lines and fluid lines for being complementary to a second connection interface of a process valve actuator of the process valve, such that the safety module can be retrofitted in the process valve; and
at least one safety valve and fluid lines provided for fluidically coupling the safety valve to the drive module and the process valve actuator of the process valve,
wherein the at least one safety valve of the safety module is configured for forced venting of the process valve in a safety case, and
wherein the first interface includes a first connection face and the second interface includes a second connection face, wherein the first and second connection faces are oriented in opposite directions.
